Maybe the errors are from the smilies in your code. Click edit on your post and check the box to disable the smilies. I hope you get a real answer to your question, but I don't know c++. You may also want to look into the code tags.
["code"]
code here
["/code"]
without the quotes of course. Good luck.

i personally think that the errors make perfect sense...i havent fully looked through your code and understood all of it, but your error report sounds like you made little errors here and there. if there is an error you dont understand, then just click on it and then click F1 and normally a little help window will pop up and will explain to you what the error is and sometimes how to fix it. Also, the comments in spanish dont help me understand the code you might want to change them to enlish porque mi espanol es muy malo
